Log Message:
x11/qt6ct: rebasing again.

The original project was resurrected on opencode.net [0].
Apparently, the Github repo was not archived upon author's will, but due
to Github suspending of Russian devs [1].

The qt6ct fork we had packaged until now primarily targets KDE [2] (not
something which pkgsrc is really concerned with for the moment), so it
makes sense to switch back to the original upstream, which just released
a 0.10 version with the following changelog:

Version 0.10
* reworked color settings
* fixed issue with app-specific palette (John Lindgren)
* fixed .desktop file name (Marcus Britanicus)
* fixed CMake warning
* enabled QPlatformTheme::HoverEffect hint
* increased minimum Qt version to 6.2
* code refactoring and optimization
* moved home page to opencode.net
* updated Dutch translation (Heimen Stoffels)
* updated Polish translation (Marek Adamski)
* updated Russian translation
